Is tapioca - the gluten-free, fat-free source of the crepes at TAP - a “healthy superfood,” as it says inside this bright Upper West Side Cafe? We have no reason to doubt it. Now, whether that still holds when you stuff them with steak and cheese or Nutella and banana, is another story. Regardless, they’re delicious. Despite disintegrating when you bite into it, the mild tapioca shell holds a lot of substantial ingredients inside, like housemade pulled pork and pineapple chutney, or stretchy queijo coalho and juicy tomatoes.
